Ever wanted a engine that can run off the heat from your coffee cup?
Like toys that are hard to explain and amazing to watch? Like precision
pieces of equipment that are beautifully engineered? Love science? Want a
gift for the person that has everything? If so you will want a Stirling
Engine.

These Stirling engines are fully assembled and not a kit, you will not find a precision Stirling Engine for a lower price.

These
are the low temperature versions of a Stirling engine that can run off
hot water from a coffee cup, heat from a router, and so on.This model has been known to run while sitting in the sun. Stirling engines
operate by using a external heat source rather than a internal heat like
a normal engine.

This model uses a clear plastic base so that the operation of the chamber can be viewed easily.

The easiest way to use them is get your normal
cup of coffee in the morning, put the Stirling engine on top of the
coffee cup, give it a slight push to get it going and as long as the
coffee is hot it will continue to run. These are precision pieces of
equipment but are finally available at a economical price.
